Radiofrequency neurotomy

The radio frequency neurotomy ( Syn. : Percutaneous radiofrequency denervation ) is a method of treatment for pain relief for back pain in the lower lumbar spine and sacroiliac joint . The aim of the treatment is the thermal destruction of the pain-conducting nerves ( neurotomy or denervation ).

With the help of a computer tomograph (imaging monitoring), a needle or probe is brought to the nerves to be treated. Heat is generated via radio waves (80–90 ° C for 60–90 seconds), which flows to the nerves and thereby interrupts the nerve pathways that conduct pain . This method is one of the methods that block nerve conduction. With 36.4% of the patients treated (pain reduction of at least 50% over at least 6 months), their response rate is quite manageable, long-term results are still lacking. Infections, hematomas, burns or damage to the surrounding nerve structures are known complications.

development

Radiofrequency neurotomy was developed in the early 1970s with the aim of interrupting the nerve supply to the facet joints of the spine . It was less fraught with undesirable side effects than the percutaneous thermocoagulation used shortly before (1970) with identical objectives .
